[FFmpeg-user] ffmpeg how to output multiple file

[Jason Runta]

It can. See this article for more information:
http://ffmpeg.org/trac/ffmpeg/wiki/Creating%20multiple%20outputs

The important part is the tee command and getting the mappings correct.
Here's an example I was using to test:

ffmpeg -y -f dshow -s 640x480 -r 29.97 -i video="Microsoft LifeCam
Cinema":audio="Desktop Microphone (Cinema - Mi" -c:v libx264 -preset
ultrafast -b:v 800k -c:a aac -strict experimental -ar 44100 -b:a 56k -f tee
-map 0:0 -map 0:1 "[f=rtsp] -rtscp_transport tcp
rtsp://localhost:1234/live.sdp|C:\\users\\jasonr\\mymovie.mkv"

and then using ffplay I could watch my stream using:
ffplay -rtsp_flags listen rtsp://localhost:1234/live.sdp
